Problems solved by technology

If the tester does not have high knowledge of building structure and corresponding technology and experience, he often does not know where to start in actual operation. Even if the gas sensor captures a certain concentration of gas induction in a certain part, it may not be sure that the is the exact location of the leak
Second, because this measurement method uses local point measurement,

Embodiment 1

[0050] Such as figure 1 , figure 2 and image 3 As shown, water leakage occurred on the top of a flat-roofed industrial plant. The roof of the factory building is a membrane waterproof roof, and the roof structure layer is a prefabricated reinforced concrete slab, which is filled with fine stone concrete, and the concrete slab is leveled with a cement mortar leveling layer. A membrane waterproof layer is laid on the cement leveling layer, and finally 20mm thick cement mortar is used as the surface protection layer. After investigation, the location of the indoor water leakage point is near the downpipe and close to one side of the wall.

[0051] For the above leaks, take the following detection and plugging methods. The steps are:

[0052] Step (1): Visual inspection of the status quo.

[0053] First, conduct a field survey of the leaking condition of the indoor roof and the current status of the roof near the leaking location through visual observation. Grasp the indo...

Embodiment 2

[0069] Such as figure 1 , figure 2 and image 3 As shown, a concrete building has water leakage from the wall. Cracks are found at the leaking point of the indoor wall, and dark tiles are pasted on the outer wall, but no abnormal phenomenon can be seen by naked eye observation.

[0070] For the above example, the method of determining plugging is as follows:

[0071] Step (1): Visual inspection of the status quo.

[0072] Observe the situation of the indoor water leakage point. If there is a plaster layer on the surface of the water leakage point, remove it so as to observe the actual conditions such as cracks, cracks or honeycombs in the concrete pouring wall.

[0073] Step (2): Status determination records.

[0074] Use infrared thermal imaging camera and wave measuring instrument to measure the condition of the external wall near the water leakage point. Mark the region where the temperature is abnormal and the wave velocity change.

[0075] Step (3): Change in air s...

Abstract

The present invention discloses a detection method of concrete building water leakage. The method comprises the steps of (1) current condition visual examination, (2) current condition measurement record, (3) aspiration measurement change, (4) the connection of a wave metre and an infrared detector, the determination of the position of a water leakage source and a water leakage path, and the determination of a water leakage serious degree by using the wave metre. The invention provides a leakage blocking method which comprises the steps of (1) drilling a waterproof layer grouting hole, (2) carrying out grouting to make a new waterproof layer, (3) making a leakage repairing reinforced grouting hole in concrete, (4) carrying out internal leakage repairing reinforced grouting, (5) sealing the water inlet of a water leakage source, and filling a water leakage path according to the water leakage serious degree. Compared with the prior art, the methods have the advantages that by using the detection and leakage blocking methods, the leakage blocking method is excellent, the defect degree of an existing concrete structure is accurately judged and the reinforcement of the concrete structure at a later period can be accurately repaired, and thus the durability of concrete is improved to play a significant role.

Description

technical field [0001] The invention relates to a measurement technology and a reinforcement and repair method, in particular to a method for detecting and plugging water leakage in concrete buildings. Background technique [0002] At present, for concrete buildings, the leak detection and plugging method that uses more leaks is Japan's Jiang Tian type leak diagnosis and repair system. [0003] Jiangtian-style water leakage diagnosis method, using carbon dioxide (CO 2 ) sensory method to detect the source of water leakage. The steps are: firstly drill a hole in the leaking part of the concrete building, send in carbon dioxide gas, and then conduct gas sensing outside the building, that is, carry out detection of sending in carbon dioxide gas at the part that is preliminarily judged to have a higher possibility of water leakage. know the measurement. Finally, according to the sensing condition of the gas sensor, the source of the water leakage, that is, the position of the...
